SSI XR Trimix (45m)
July 6, 2025 - July 10, 2025

The SSI Extended Range (Trimix 45m) course includes everything you learned in the previous Extended Range Nitrox and Air 45m modules, but here you also learn the techniques and procedures for using trimix breathing gases. This course can either be done using double tanks or on sidemount.
Upon completion, this program certifies divers:
- to independently plan and conduct trimix decompression dives up to 45m
- to use decompression gas mixtures of up to 100% oxygen
- to have a maximum accumulated decompression time of 25 minutes
